by taking off the cap F; also, the conical construction of the backs ofthe gates O 0 provides for the passage of any obstruction getting inbetween them to the space '5 beneath, so that the gates are at fullliberty to seat themselves.

A straight-way valve constructed as described essentially differs fromothers in which a screw-stem has connected with it toggle-levers thatnot only raise or lower opposite gates or valve-disks, but thrust thesame outward against their seats; also from a slotted tubular valveprovided with one or more inlets, and which is opened against thevresistance of the fluid by a wedge-shaped key operated by a spindle.

The tubular devices B B, it will be observed, not only formexternally-removable gate-seats, but also couplings for connecting theinlet an outlet pipes with the valve.

I I am aware that it is not newtto makestraight- 20 way valves, arrangethem in a valve-box movable up and down by a screw, and to clamp themagainst their seats by an upper wedge on the valve-box and a bottomwedge on the body, of thevalve-chamber but 2 5 What I do claim as newand of my inven tion is The combination, with the valve-body A, of theslotted sliding wedge D, the side or end gates, O O, freely fittedthereto, and constructed 0 with conical backs c c, the beveledguide-ribs k k, and the gate-seats B B, substantially as described.
